I need to get WinRM working for three Windows Server 2008 R2 (SP1) machines. They are running Microsoft Exchange on them. I run Windows Powershell as an Administrator and type "winrm qc", the following is then printed

PS C:\Windows\system32> winrm qc
WinRM already is set up to receive requests on this machine.
WSManFault
Message = The WinRM client sent a request to an HTTP server and got a response saying the requested HTTP URL was not
available. This is usually returned by a HTTP server that does not support the WS-Management protocol.
Error number: -2144108269 0x80338113
The WinRM client sent a request to an HTTP server and got a response saying the requested HTTP URL was not available. Th
is is usually returned by a HTTP server that does not support the WS-Management protocol.

The same error message is printed when I stop and then start the WinRM service.

The http iplist is empty and if I add 127.0.0.1 to it the same error message is printed when running winrm qc.
